Chevron Issues Interim Update for Fourth Quarter 2009

SAN RAMON, Calif., January 11, 2010 – Chevron Corporation (NYSE:CVX) today reported in its interim update that earnings for the fourth quarter 2009 are expected to be lower than in the third quarter 2009. Upstream earnings are projected to be in line with third quarter results as the benefit of higher commodity prices is offset by the absence of gains recognized in the third quarter associated with formal approval of the Gorgon project in Australia. Downstream results are expected to be sharply lower, mainly due to significantly weaker refining margins.
